Comparison of anti-interference ability between MPC and Robust Control

This paper proposes two controllers for a gas collector system with two inputs and two outputs. Firstly, the system model is obtained through global data system identification. Then, the MPC controller and robust controller are designed for this model. The robust controller proposed in this paper is the stateback controller, and the robust controller is designed by the linear matrix inequality technique. Both controllers have their own advantages, but their ability to suppress disturbances is different, which is the main issue to be discussed in this article. Under the same external interference, the comparison between two controllers are obtained. At last, the simulation is demonstrated to show the effectiveness of two controllers.
